Transferring connector elements into Abaqus/Explicit

This problem contains basic test cases for one or more Abaqus elements and features.

The verification of the import functionality of the connector elements is based on the analyses covered in Connector element verification. Typically, the Abaqus/Standard analyses covered in that section are imported and continued using Abaqus/Explicit. The results from Abaqus/Explicit at the point of import are compared with those from Abaqus/Standard. The analyses are continued by importing from the Abaqus/Explicit analyses to new Abaqus/Explicit analyses, and the results at the point of import are compared.

The connector elements can be imported from Abaqus/Standard or Abaqus/Explicit to Abaqus/Explicit. The import of connector elements to Abaqus/Standard is not available.

Problem description

See Damped free vibration with initial conditions for the problem description. The connector elements are imported, and any mass and rotary inertia elements in the model are redefined. Various types of connector sections are tested. The connector behavior includes elasticity and damping.

Results and discussion

The results demonstrate that the connector elements are transferred successfully from Abaqus/Standard to Abaqus/Explicit.

Problem description

See Tests for special-purpose connectors for the problem descriptions covering the SLIPRING-type connectors with and without friction and the RETRACTOR-type connectors. The connector elements are imported, and any mass and rotary inertia elements in the model are redefined. The connector behavior includes elasticity, plasticity, and friction.

Results and discussion

The results demonstrate that the connector elements are transferred successfully from Abaqus/Standard to Abaqus/Explicit.
